Class
    Foam::uniformInletOutletEnergyTemperatureFvScalarFieldSource

Description
    This source condition is applied to the temperature field, but provides a
    uniform fixed energy into the energy equation when the source is positive,
    and the internal value when it is negative (i.e., a sink)

Usage
    \table
        Property       | Description                | Required | Default value
        uniformInletHe | uniform inlet energy value | yes      |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <sourceName>
    {
        type            uniformInletOutletEnergyTemperature;
        uniformInletHe  3700000;
    }
    \endverbatim
